  1. ncbi Cortical activation during Pavlovian fear conditioning depends on heart rate response patterns: an MEG study
    Stephan Moratti
    Department of Psychology, University of Konstanz, P O Box D25, D 78457 Konstanz, Germany
    Brain Res Cogn Brain Res 25:459-71. 2005
    ..The results suggest that participants expressing different HR responses also differ in their stimulus-driven neuromagnetic response pattern to an aversively conditioned stimulus...
  2. ncbi Fear but not awareness predicts enhanced sensory processing in fear conditioning
    Stephan Moratti
    Department of Psychology, University of Konstanz, Konstanz, Germany
    Psychophysiology 43:216-26. 2006
    ..Participants in both groups reported awareness of CS-US contingencies. Awareness of stimulus contingency in fear conditioning seems not to be sufficient to elicit enhanced visual cortical processing...
  3. ncbi Motivated attention in emotional picture processing is reflected by activity modulation in cortical attention networks
    Stephan Moratti
    Department of Psychology, University of Konstanz, Constance, Germany
    Neuroimage 21:954-64. 2004
    ..Taken together, we argue that activity in higher-order frontoparietal cortical attention networks is modulated by emotional arousal. In turn, this attention network influences activity in systems performing stimulus processing...
  4. ncbi Additive effects of emotional content and spatial selective attention on electrocortical facilitation
    Andreas Keil
    Department of Psychology, University of Konstanz, Germany
    Cereb Cortex 15:1187-97. 2005
    ..The data suggest that affective stimulus properties modulate the spatiotemporal process along the ventral stream, encompassing amplitude amplification and timing changes of posterior and temporal cortex...
  5. ncbi Modulation of the C1 visual event-related component by conditioned stimuli: evidence for sensory plasticity in early affective perception
    Margarita Stolarova
    University of Konstanz, Konstanz, Germany
    Cereb Cortex 16:876-87. 2006
    ..As an underlying mechanism, we discuss short-term reorganization in visual cortex, enabling sensory amplification of specific visual features that are related to motivationally relevant information...
  6. ncbi Early modulation of visual perception by emotional arousal: evidence from steady-state visual evoked brain potentials
    Andreas Keil
    Department of Psychology, University of Konstanz, Konstanz, Germany
    Cogn Affect Behav Neurosci 3:195-206. 2003
    ..These findings are consistent with reentrant modulation of early visual processing by distributed networks including subcortical and neocortical structures according to a stimulus's motivational relevance...

    Nathan Weisz

  11. pmc Adaptation in human visual cortex as a mechanism for rapid discrimination of aversive stimuli
    Andreas Keil
    NIMH Center for the Study of Emotion and Attention, University of Florida, Gainesville, FL 32611, USA
    Neuroimage 36:472-9. 2007
    ..Our findings suggest that reorganization of neural connectivity on the level of the visual cortex acts to optimize early perception of specific features indicative of emotional relevance...
